This is the “EOD” set point menu. The user can set the value that the charger will give the “EOD”
fault. This is factory set at voltage per cell but can be changed to voltage (of the entire battery
set). (Factory set @ 1.70V/C with a range of 1.00 to 2.00V/C)
Set GFI Open
This is the Ground Fault Indicator (GFI) set point menu. The user can set the leakage current
threshold value with a resistor. This sets the value that will cause the charger to give the “GFI +”
or “GFI –“ faults. (Factory set with a 10k-ohm resistor).
To set the “GFI” set points, do the following:
1) Determine what value of resistance the set point will be changed to and have a resistor of
that value available with leads ready to use. (Charger factory set with a 10k-ohm resistor)
2) When the display reads “Set GFI Open” and there is no resistor on Positive or Negative
battery to Chassis Ground, press the RIGHT ARROW button.
3) The display reads “Set GFI Pos”. Place the resistor between Battery Positive and Chassis
Ground and wait 5 seconds, then press the RIGHT ARROW button.
4) The display reads “Set GFI Neg”. Place the resistor between Battery Negative and Chassis
Ground and wait 5 seconds, then press the RIGHT ARROW button.
5) The display should have “Set GFI Open” on it.
A) If it does, remove the resistor from the Battery Negative, then press LEFT ARROW
button.
B) If it reads, “GFI Set Fault”, there is a problem. Repeat steps 1 through 5.
6) The display reads “Alarm Settings”. Press the LEFT ARROW button again to get to the
default display menu.
This resistance is the set point for the “GFI” fault. The fault will have a resistance window that will
trigger the fault. To test the fault, you may need a resistance less than the set point value.
11.3.5 EQLZ SETTINGS (EQUALIZE SETTINGS)
The Equalize Settings menu allows the user to set up the length of time an equalize cycle is
active, the interval or time between equalize cycles, the type of equalize mode, and the charge
mode that the charger starts in. The menus are explained in the following sections.
Eqlz Time (Equalize Time)
This menu sets the amount of time the Equalize mode of charging is set to run before it will return
to float mode automatically. This time will be shown on the Default display as “Hrs Left” and
count down until the Equalize charge returns to float charge. (Factory set @ 1hr with a range of 1
to 255hrs)
Eqlz Int (Equalize Interval)
This menu sets the interval between Automatic equalizing charges. The charger will start
counting down when the equalizing mode Auto/Auto is selected. (Factory set @ 1Day with a
range of 1 to 180 Days)
Mode (Equalize Mode)
This menu allows the user to choose one of the three Equalize mode selections explained in
the following sections. (Factory set at Manual/Automatic.)
1) Man/Man (Manual/Manual)
In this mode the user must press and hold the “HOLD TO EQUALIZE” button to manually
start an Equalize charge mode. The default display will show, “Manual Eqlz”. To stop the
equalize charge mode the user must press and hold the “HOLD TO EQUALIZE” button until it
stops and returns to Float Mode.
2) Man/Auto (Manual/Automatic)
In this mode the user must press and hold the “HOLD TO EQUALIZE” button to manually
start an Equalize charge mode. The charger will charge in the Equalize mode for the amount
of time in the Equalize Time menu, then automatically return to the FLOAT mode. The
